shoulder blade
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
Where is coracoid process located?
The coracoid process is a hook-shaped bone structure projecting anterolaterally from the superior aspect of the scapular neck.
Where is the acromion process of scapula?
shoulder
In human anatomy, the acromion (from Greek: akros, “highest”, ōmos, “shoulder”, plural: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly.
Where do we find acromion and Metacromion processes?
The scapula bears two marked processes: the acromion and, rather less obvious, the coracoid. The acromion springs like the head of a golf club from the spine of the scapula, extends anterior to the glenoid fossa and carries a small subsidiary process, the metacromion.
Where is the humerus bone located?
humerus, long bone of the upper limb or forelimb of land vertebrates that forms the shoulder joint above, where it articulates with a lateral depression of the shoulder blade (glenoid cavity of scapula), and the elbow joint below, where it articulates with projections of the ulna and the radius.
Where do you find acromion bone?
At the far end of the spine, the acromion forms where the bone widens significantly and extends anteriorly to cover the superior aspect of the shoulder joint. The acromion is a flat bony projection and has a rectangular shape with rounded corners.
Where is the acromion process and how would you locate it?
The acromion process is the part of our shoulder blade, or scapula, that you can feel sticking up if you rub where the back of your shoulder meets your arm.
Where is the upper trapezius located?
The trapezius is one of the broadest and most superficial (closest to the skin) muscles of the upper back and trunk, meaning upon dissection of a cadaver it is often used as a landmark because it is encountered first. This muscle is triangular, broad, and thin and covers the upper back of the shoulders and neck.
Where is the latissimus dorsi muscle located?
The latissimus dorsi muscle is found superficially in the lower two-thirds of the trunk, covering the serratus posterior muscles. The teres major muscle lies superior to latissimus dorsi. The adjoining fibers of these two muscles are united, but separated by a bursa towards their humeral attachments.
What is the structure of the coracoid process of the scapula?
Structure. The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; it runs at first upward and medialward; then, becoming smaller, it changes its direction, and projects forward and lateralward. The ascending portion, flattened from before backward,…
What is a coracoid process fracture?
Coracoid process fractures are an uncommon type of scapular fracture. They do not often occur in isolation and are often associated with acromial, clavicular, or other scapular fracture, as well as glenohumeral dislocation or acromioclavicular joint injury .
What is a coracoid process in the humerus?
CIS describes when the coracoid process is thought to physically impinge upon the lesser tuberosity of the humerus, pinching the subscapularis tendon and perhaps the long head of the biceps tendon in the process, thus causing pain and/or degeneration of said structures.
What is coracoid impingement of the shoulder?
“Coracoid impingement is a rare cause of anterior shoulder pain, which should be considered especially after the failure of previous surgery for impingement, biceps tendon lesions, instability, or an operation on the coracoid…” Interesting, in this paper was the rareness of the CIS, 7 patients in 6 years.
